As for your friend, I'd start testing the "waters" so to speak. You might get lucky. But on you other points, its hard being a closeted BI. Sounds weird but it is.
I like making new friends, gay, BI, Straight. Neither
Please feel free to ask me anything, I'm not a shy guy.
BTW I am BI and love to talk/friend other Gay/BI guys. If your in Oregon USA, that's even better
